This invention relates to that well-known class of sawing-machines which embody a circular saw, a pendulous bolt-carriage which is swung to and fro by the operator for carrying the bolt against the saw and back, and a gage which is arranged on one side of the bolt-carriage and against which the bolt is pressed by the operator before each cutting movement of the bolt-carriage for producing a uniform thickness of the cut slabs. The gage in these sawing-machines is adjustable toward and from the bolt-carriage for regulating the thickness of the cut. It is, however, often desirable to cut off a slab of greater thickness for the purpose of removing an imperfect portion of the bolt—for instance, a knot—and in other cases it is desirable to cut off slabs of less thickness than those for which the gage is set. The main object of this invention is to provide means for moving the gage quickly out of its normal position either from or toward the saw-carriage for taking a thicker or thinner cut than that for which the gage is set and returning the gage quickly to its normal position when such unusual cut has been taken. Another object of the invention is to provide simple means for regulating the distance through which the gage can be moved out of its normal position and the thickness of the unusual or emergency cut produced thereby.

We claim as our invention—

1. The combination of a saw, a bolt-carriage, a gage movable bodily toward and from the bolt-carriage, mechanism for moving the gage out of a normal position with reference to the line of cut and the bolt-carriage and for returning the gage to this normal position, and means for stopping the return movement when the gage reaches said normal position, substantially as set forth.

2. The combination of a saw, a bolt-carriage, a gage movable bodily toward and from the bolt-carriage, means for moving the gage out of a normal position with reference, to the line of cut and the bolt-carriage, means for returning the gage, and a stop to limit said return movement, substantially as set forth.

3. The combination of a saw, a bolt-carriage, a gage movable toward and from the bolt-carriage, a lever connected to said gage, a treadle connected to said lever for moving the gage in one direction, a spring for returning said gage, and a stop for limiting said return movement, substantially as set forth.

4. The combination of a saw, a-bolt-carriage, a gage movable bodily toward and from the latter, a stop for fixing the normal position of the gage with reference to the line of cut and the bolt-carriage, means for shifting the gage bodily to an abnormal position, a stop for fixing this abnormal position of the gage, and means for returning the gage to its normal position, substantially as set forth.

5. The combination of a saw, a bolt-carriage, a stationary frame, gage-frame mounted in said stationary frame to move bodily toward and from said carriage, gage members adjustably attached to said gage-frame, means for moving said gage-frame and the gage members carried thereby bodily in one direction, means for returning the gage-frame, and means for arresting the return movement of the gage-frame in the normal position of the latter, substantially as set forth.

6. The combination of a saw, a bolt-carriage, a stationary frame, a gage provided with a horizontal rod which is capable of sliding in said stationary frame, a lever pivoted to said stationary frame, a link connecting the lever with said gage-frame, a treadle for moving said gage out of a normal position, a link connecting the treadle with said lever, means for returning said gage, and means for stopping, the return movement of the gage when said normal position is reached, substantially as set forth.

7. The combination with a stationary frame, a saw, a bolt-carriage, a gage slidably mounted on said frame to move toward and from said carriage, a lever pivoted on said frame, a link connecting said lever and said gage, a treadle connected to said lever for moving said gage away from the carriage, means for returning said gage, a rod connected to said gage and passing through an opening in a part of said frame, and an adjusting-stop carried by said rod and adapted to engage said frame to limit the return movement of the gage, substantially as set forth.

8. The combination of a saw, a bolt-carriage, a gage movable bodily toward and from said bolt-carriage, means for moving the gage away from said carriage, an adjustable stop device for limiting the movement away from the carriage, means for returning the gage, and a stop for limiting said return movement, substantially as set forth.

9. The combination of stationary frame, a saw, a bolt-carriage, a gage movably mounted on said frame to move toward and from said bolt-carriage and provided with a stop, a regulating-wedge for determining the movement of said gage, said wedge being movable in the path of said stop, and means for holding said regulating-wedge in its adjusted position, substantially as set forth.

10. The combination of a stationary frame, a saw, a bolt-carriage, a gage movably mounted on said frame to move toward and from said bolt-carriage, a pivoted regulating-wedge for determining the movement of said gage, a stop carried by said gage, said wedge being arc-shaped and movable in the path of said stop, and means for holding said regulating-wedge in its adjusted position, substantially as set forth.
